Trivia

At first, for the voice of Homer Simpson, Castellaneta tried to imitate Walter Matthau, but he had trouble with certain emotional registers and intonations with the voice, so he slightly changed the present voice of Homer at the beginning of the second season of The Simpsons (1989).

His voice characterization of Krusty the Clown on The Simpsons was based on Chicago television legend Bob Bell, who portrayed WGN-TV's "Bozo" from 1960 to 1984.
